Subtitle content 308 are provided as part of the audiovisual content 302 and include the subtitle text as well as timing information. The timing information may include, but is not limited to, the starting time and the end time of a particular subtitle, the starting time and the duration of the particular subtitle, or provide relative time information between one subtitle and the other. Regardless of the particular format, the subtitle content 308 is provided to the subtitle analyzer 330. The subtitle analyzer 330 extracts the timing information for each subtitle segment STi. The subtitle and human voice misalignment analyzer 340 receive both the human voice segments HAi and the STi segments and respective timing information. It then performs an analysis to determine the nature of the correction and as further explained with respect of FIGS. 4 and 5. Based on the determination, and as further discussed with respect of FIGS. 4 and 5, a set of correction factors may be provided to the subtitle and audio content alignment unit 350. The correction factors may be such that no alignment correction is necessary, such as in the case shown with respect of FIG. 2A, that a correction is needed and may be performed by the system as it is within its capabilities between predetermined thresholds and then providing a set of correction factors to the subtitle and audio content alignment unit 350, which includes the cases shown in FIGS. 2A-2C, or, a determination that correction is not possible and providing an error notification signal on the notification signal 345. Notification signal 345 may further be used to provide other kinds of notifications including that no correction is needed, or when a correction is needed notifying of the type of correction performed. It should be noted, as also mentioned herein that the correction factor may be a constant or, if TΔ continuously increases or continuously decreases, a set of correction factors that changes continuously over time.
